背景：青年时期是酗酒和暴饮暴食的高危时期，这两种情况都会影响体重并导致肥胖。研究饮酒和食用可口食物的动机可能有助于更全面地了解大学期间的这些行为。目前的研究测试了是否共享或不同（即，行为特异性）的动机机制可以解释奖励驱动的饮酒和饮食在年轻adult.Methods：大学新生（N = 103）分层的性别，种族/民族，和大量饮酒状态的样本被选中参加。参与者完成了测量饮酒，饮食行为和动机的问卷调查，由饮酒动机量表修订版和美味的饮食动机量表评估。验证性因素分析（CFA）测试是否饮酒和饮食的动机更好地表示为单一的潜在动机，或两个行为的具体动机。结果：行为特异性CFA模型比单一动机模型具有更强的模型拟合度和更高的因子负荷。SEM模型表明，通过进食来科普负面情绪、增强积极体验、获得社会强化以及与同伴保持一致与暴饮暴食显著相关（p值
Background: Young adulthood is a high-risk period for heavy drinking and binge eating, both of which can impact weight and lead to obesity. Examining motives for drinking alcohol and eating palatable foods may facilitate a more integrated understanding of these behaviors during the college years. The current study tested whether shared or distinct (i.e., behavior-specific) motivational mechanisms may explain the occurrence of reward-driven drinking and eating in young adults.Methods: A sample of college freshmen (N = 103) stratified by sex, race/ethnicity, and heavy drinking status were selected to participate. Participants completed questionnaires measuring alcohol use, eating behavior, and motives assessed by the Drinking Motives Questionnaire-Revised and Palatable Eating Motives Scale. Confirmatory factor analysis (CFA) tested whether drinking and eating motives were better represented as single latent motives, or two behavior-specific motives. Structural equation modeling (SEM) was used to test the association between motivational factors and behaviors.Results: Behavior-specific CFA models demonstrated stronger model fit and higher factor loadings than single motive models. SEM models indicated that eating to cope with negative emotions, to enhance positive experiences, to obtain social reinforcement, and to conform with peers were significantly associated with binge eating (p values
